[Bilateral iris coloboma].

Congenital ocular colobomas are due to incomplete closure of the fetal fissure during organogenesis. Ocular involvement can be variable ranging from a simple hole in the iris to a more severe involvement of the posterior pole (coloboma of the optic nerve, of the choroid, of the retina). We here report the case of a typical isolated bilateral iris coloboma. The study involved a 55-year old woman who discovered a typical inferonasal iris coloboma without involvement of the crystalline or of the posterior pole on ophthalmologic examination.
